ABSTRACT
Indigenous communities in the North American Arctic are characterized by mixed economies that feature hunting, fishing, gathering, and trapping activities-and associated sharing practices-alongside the formal wage economy. The region is also undergoing rapid social, economic, and climate changes, including, in Canada, carbon taxation, which is impacting the cost of fuel used in local food harvesting. Because of the importance of local foods to nutrition, health, and well-being in Arctic Indigenous communities, there is an urgent need to better understand the sensitivity of Arctic food systems to social, economic, and climate changes and to develop plans for mitigating potential adverse effects. Here, we develop a Bayesian model to calculate the substitution value and carbon emissions of market replacements for local food harvests in the Inuvialuit Settlement Region, Canada. Our estimates suggest that under plausible scenarios, replacing locally harvested foods with imported market substitutes would cost over 3.1 million Canadian dollars per year and emit over 1,000 tons of CO2-equivalent emissions per year, regardless of the shipping scenario. In contrast, we estimate that gasoline inputs to harvesting cost approximately $295,000 and result in 315 to 497 tons of emissions. These results indicate that climate change policies that fail to account for local food production may undermine emissions targets and adversely impact food security and health in Arctic Indigenous communities, who already experience a high cost of living and high rates of food insecurity.

OBJECTIVE: To evaluate differences in the percentage of expenditure on food groups in Mexican households according to the gender of the household head and the size of the locality. DESIGN: Analysis of secondary data from the National Household Income and Expenditure Survey (ENIGH) 2018. We estimated the percentage of expenditure on fifteen food groups according to the gender of the head of household and locality size and evaluated the differences using a two-part model approach. SETTING: Mexico, 2018. PARTICIPANTS: A nationally representative sample of 74 647 Mexican households. RESULTS: Female-headed households allocated a lower share of expenditure to the purchase of sweetened beverages and alcoholic beverages and higher percentages to milk and dairy, fruits and water. In comparison with metropolitan households, households in rural and urban localities spent more on cereals and tubers, sugar and honey, oil and fat and less on food away from home. CONCLUSIONS: Households allocate different percentages of expenditure to diverse food groups according to the gender of the head of the household and the size of the locality where they are located. Future research should focus on understanding the economic and social disparities related to differences in food expenditure, including the gender perspective.

BACKGROUND: Environmental factors can impact the ability of food retail businesses to implement best practice health-enabling food retail. METHODS: We co-designed a short-item survey on factors influencing food retail health-enabling practice in a remote Australian setting. Publicly available submissions to an Australian Parliamentary Inquiry into food pricing and food security in remote Indigenous communities were coded using an existing remote community food systems assessment tool and thematically analysed. Themes informed survey questions that were then prioritised, refined and pre-tested with expert stakeholder input. RESULTS: One-hundred and eleven submissions were coded, and 100 themes identified. Supply chain related data produced the most themes (n = 25). The resulting 26-item survey comprised questions to assess the perceived impact of environmental factors on a store's health-enabling practice (n = 20) and frequency of occurrence (n = 6). CONCLUSIONS: The application of this evidence-informed, co-designed survey will provide a first-time cross-sectional analysis and the potential for ongoing longitudinal data and advocacy on how environmental factors affect the operations of remote stores.

BACKGROUND: The WHO highlight alcohol, tobacco, unhealthy food, and sugar-sweetened beverage (SSB) taxes as one of the most effective policies for preventing and reducing the burden of non-communicable diseases. This umbrella review aimed to identify and summarise evidence from systematic reviews that report the relationship between price and demand or price and disease/death for alcohol, tobacco, unhealthy food, and SSBs. Given the recent recognition as gambling as a public health problem, we also included gambling. METHODS: The protocol for this umbrella review was pre-registered (PROSPERO CRD42023447429). Seven electronic databases were searched between 2000-2023. Eligible systematic reviews were those published in any country, including adults or children, and which quantitatively examined the relationship between alcohol, tobacco, gambling, unhealthy food, or SSB price/tax and demand (sales/consumption) or disease/death. Two researchers undertook screening, eligibility, data extraction, and risk of bias assessment using the ROBIS tool. RESULTS: We identified 50 reviews from 5,185 records, of which 31 reported on unhealthy food or SSBs, nine reported on tobacco, nine on alcohol, and one on multiple outcomes (alcohol, tobacco, unhealthy food, and SSBs). We did not identify any reviews on gambling. Higher prices were consistently associated with lower demand, notwithstanding variation in the size of effect across commodities or populations. Reductions in demand were large enough to be considered meaningful for policy. CONCLUSIONS: Increases in the price of alcohol, tobacco, unhealthy food, and SSBs are consistently associated with decreases in demand. Moreover, increasing taxes can be expected to increase tax revenue. There may be potential in joining up approaches to taxation across the harm-causing commodities.

Purpose: This study aimed to assess the reliability and validity of an online approach to monitoring food affordability in Ontario using the updated Ontario Nutritious Food Basket (ONFB).Methods: The ONFB was priced online in 12 large multi-chain grocery stores to test intra-/inter-rater reliability using percent agreement and intra-class correlations (ICCs). Then, the ONFB was priced in-store and online in 28 stores to estimate food price differences using paired t-tests and Pearson's correlation for all (n =1708) and matched items (same product/brand and purchase unit) (n = 1134).Results: Intra-/inter-rater agreement was high (95.4%/81.6%; ICC = 0.972, F = 69.9, p < 0.001). On average, in-store prices were less than $0.02 lower than online prices. There were no significant differences between mean in-store and online prices for all items (t = 0.504 p = 0.614). The mean price was almost perfectly correlated between in-store and online (fully matched: R = 0.993 p < 0.001; all items: R = 0.967 p < 0.001). Online monthly ONFB estimates for a family of four were strongly correlated (R = 0.937 p < 0.001) with estimates calculated using in-store data.Conclusions: Online pricing is a reliable and valid approach to food costing in Ontario that contributes to modernizing the monitoring of food affordability in Canada and abroad.

BACKGROUND: Malnutrition poses a substantial challenge in Somalia, impacting approximately 1.8 million children. This critical issue is exacerbated by a multifaceted interplay of factors. Consequently, this study seeks to examine the long-term and short-term effects of armed conflicts, food price inflation, and climate variability on global acute malnutrition in Somalia. METHODS: The study utilized secondary data spanning from January 2015 to December 2022, sourced from relevant databases. Two distinct analytical approaches were employed to comprehensively investigate the dynamics of global acute malnutrition in Somalia. Firstly, dynamic autoregressive distributed lag (ARDL) simulations were applied, allowing for a nuanced understanding of the short and long-term effects of armed conflicts, food price inflation, and climate variability on malnutrition. Additionally, the study employed kernel-based regularized least squares, a sophisticated statistical technique, to further enhance the robustness of the findings. The analysis was conducted using STATA version 17. RESULTS: In the short run, armed conflicts and food price inflation exhibit positive associations with global acute malnutrition, particularly in conflict-prone areas and during inflationary periods. Moreover, climatic variables, specifically temperature and rainfall, demonstrate positive associations. It is important to note that temperature lacks a statistically significant relationship with global acute malnutrition in the short run. In the long run, armed conflicts and food price inflation maintain persistent impacts on global acute malnutrition, as confirmed by the dynamic ARDL simulations model. Furthermore, both temperature and rainfall continue to show positive associations with global acute malnutrition, but it is worth noting that temperature still exhibits a non-significant relationship. The results from kernel-based regularized least squares were consistent, further enhancing the robustness of the findings. CONCLUSIONS: Increased armed conflicts, food price inflation, temperature, and rainfall were associated with increased global acute malnutrition. Strategies such as stabilizing conflict-prone regions, diplomatic interventions, and peace-building initiatives are crucial, along with measures to control food price inflation. Implementing climate adaptation strategies is vital to counter temperature changes and fluctuating rainfall patterns, emphasizing the need for resilience-building. Policymakers and humanitarian organizations can leverage these insights to design targeted interventions, focusing on conflict resolution, food security, and climate resilience to enhance Somalia's overall nutritional well-being.

Switching between similar food and beverage products may reduce greenhouse gas emissions (GHGe). Here, using consumer data linked to 23,550 product-specific GHGe values, we estimated annual GHGe attributable to product purchases consumed at home in Australia and calculated reductions from specific switches. Potential changes to mean Health Star Rating, mean energy density and the proportion of ultraprocessed foods purchased were assessed. Approximately 31 million tonnes of GHGe were attributable to products consumed at home in 2019, the three highest contributors of GHGe being 'meat and meat products' (49%), 'dairy' (17%) and 'non-alcoholic beverages' (16%). Switching higher-emission products for 'very similar' lower-emission products could reduce total emissions by 26%. Switches to 'less similar' lower-emission products could lead to a 71% reduction. Switches had little impact on the average Health Star Rating, energy density of purchases and proportion of ultraprocessed foods purchased. Directing manufacturing and marketing towards lower-environmental-impact products and signposting such options to consumers are key.

Retailers have been using promotion as a differentiation strategy that influences consumers' expenditures and their shopping basket budgetary allocation. This study assessed the effect of retail promotions on total shopping basket expenditure and determined whether promotions provoke a reallocation of the shopping budget. The analysis was performed on a chain of supermarkets in Catalonia, Spain using a consumer scanner data set from Kantar Worldpanel for 2017. The methodological approach had two steps: prediction of the effect of promotion on household expenditures using an expenditure regression model and estimation of the promotion own- and cross-effect using the censored Exact Affine Stone Index. Promotion had a positive own-effect and mostly a negative asymmetric cross-effect, implying a small but significant budget reallocation.

The study examines the relationship between the corporate social responsibility (CSR) investments of a food firm, an activist's incentive to target the firm to uncover and deter fraudulent behavior, and the firm's incentive to commit food fraud. Specifically, we develop a game theoretic model to analyze the strategic interaction between a food firm that decides whether to provide a credence food attribute and whether to misrepresent the quality of its product, and an activist who decides whether to monitor the firm and launch a campaign to uncover and remove false/misleading quality claims. We further examine the effect of CSR and the activist's presence on the level of quality the firm provides. We derive the conditions under which an activist will find it optimal to monitor the firm to uncover fraudulent quality claims and the firm will find it optimal to misrepresent its product quality. Analytical results show that the greater the firm's CSR investments, the less likely it is that the activist will find it optimal to monitor the firm, and the more likely it is that the firm will find it optimal to misrepresent its product quality. Results also show that the firm is more likely to misrepresent its product quality when its effectiveness in contesting the activist's campaign is relatively high, and more likely to actually provide a high-quality product when the cost of the credence attribute is relatively low.

Importance: Point-of-sale food messaging can encourage healthier purchases, but no studies have directly compared multiple interventions in the field. Objective: To examine which of 4 food and beverage messages would increase healthier vending machine purchases. Design, Setting, and Participants: This randomized trial assessed 13 months (February 1, 2019, to February 29, 2020) of vending sales data from 267 machines and 1065 customer purchase assessments from vending machines on government property in Philadelphia, Pennsylvania. Data analysis was performed from March 5, 2020, to November 8, 2022. Interventions: Study interventions were 4 food and beverage messaging systems: (1) beverage tax posters encouraging healthy choices because of the Philadelphia tax on sweetened drinks; (2) green labels for healthy products; (3) traffic light labels: green (healthy), yellow (moderately healthy), or red (unhealthy); or (4) physical activity equivalent labels (minutes of activity to metabolize product calories). Main Outcomes and Measures: Sales data were analyzed separately for beverages and snacks. The main outcomes analyzed at the transaction level were calories sold and the health status (using traffic light criteria) of each item sold. Additional outcomes were analyzed at the monthly machine level: total units sold, calories sold, and units of each health status sold. The customer purchase assessment outcome was calories purchased per vending trip. Results: Monthly sales data came from 150 beverage and 117 snack vending machines, whereas 1065 customers (558 [52%] male) contributed purchase assessment data. Traffic light labels led to a 30% decrease in the mean monthly number of unhealthy beverages sold (mean ratio [MR], 0.70; 95% CI, 0.55-0.88) compared with beverage tax posters. Physical activity labels led to a 34% (MR, 0.66; 95% CI, 0.51-0.87) reduction in the number of unhealthy beverages sold at the machine level and 35% (MR, 0.65; 95% CI, 0.50-0.86) reduction in mean calories sold. Traffic light labels also led to a 30-calorie reduction (b = -30.46; 95% CI, -49.36 to -11.56) per customer trip in the customer purchase analyses compared to physical activity labels. There were very few significant differences for snack machines. Conclusions and Relevance: In this 13-month randomized trial of 267 vending machines, the traffic light and physical activity labels encouraged healthier beverage purchases, but no change in snack sales, compared with a beverage tax poster. Corporations and governments should consider such labeling approaches to promote healthier beverage choices. Trial Registration: ClinicalTrials.gov Identifier: NCT06260176.

School food environments contribute to children's nutritional intake and overall health. As such, the World Health Organization and other public health organizations encourage policies that restrict children's access and exposure to foods and beverages that do not build health in and around schools. This global scoping review explores the presence and characteristics of policies that restrict competitive food sales and marketing for unhealthy foods across 193 countries using evidence from policy databases, gray literature, peer-reviewed literature, and primary policy documents. Policies were included if they were nationally mandated and regulated marketing and/or competitive foods in the school environments. Worldwide, only 28% of countries were found to have any national-level policy restricting food marketing or competitive food sales in schools: 16% of countries restrict marketing, 25% restrict competitive foods, and 12% restrict both. Over half of policies were found in high-income countries. No low-income countries had either policy type. Eight marketing policies (27%) and 14 competitive foods policies (29%) lacked explicit guidelines for either policy monitoring or enforcement. Future research is needed to assess the prevalence of policies aimed at improving other key aspects of the school food environment, such as dietary quality of school meals or food procurement, as well as assess the implementation and efficacy of existing policies.

The present study aims to analyze the trends in food price in Brazil with emphasis on the period of the Covid-19 pandemic (from March 2020 to March 2022). Data from the Brazilian Household Budget Survey and the National System of Consumer Price Indexes were used as input to create a novel data set containing monthly prices (R$/Kg) for the foods and beverages most consumed in the country between January 2018 and March 2022. All food items were divided according to the Nova food classification system. We estimated the mean price of each food group for each year of study and the entire period. The monthly price of each group was plotted to analyze changes from January 2018 to March 2022. Fractional polynomial models were used to synthesize price changes up to 2025. Results of the present study showed that in Brazil unprocessed or minimally processed foods and processed culinary ingredients were more affordable than processed and ultra-processed foods. However, trend analyses suggested the reversal of the pricing pattern. The anticipated changes in the prices of minimally processed food relative to ultra-processed food, initially forecasted for Brazil, seem to reflect the impact of the Covid-19 pandemic on the global economy. These results are concerning as the increase in the price of healthy foods aggravates food and nutrition insecurity in Brazil. Additionally, this trend encourages the replacement of traditional meals for the consumption of unhealthy foods, increasing a health risk to the population.

Globalization, income growth and changing cultural trends are believed to prompt consumers in low-income countries to adopt the more affluent diet of high-income countries. This study investigates the convergence of food expenditure patterns worldwide, focusing on total food expenditure, raw food categories and ultra-processed foods and beverages across more than 90 countries over the past decades. Contrary to prior belief, we find that food expenditure patterns of lower-income countries do not universally align with those of higher-income nations. This trend is evident across most raw food categories and ultra-processed foods and beverages, as the income level of a country continues to play a crucial role in determining its food expenditure patterns. Importantly, expenditure patterns offer estimates rather than a precise idea of dietary intake, reflecting consumer choices shaped by economic constraints rather than exact dietary consumption.

INTRODUCTION: Evidence for the effect of neighbourhood food environment (NFE) exposures on diet in the UK is mixed, potentially due to exposure misclassification. This study used the first national COVID-19 lockdown in England as an opportunity to isolate the independent effects of the NFE exposure on food and drink purchasing, and assessed whether these varied by region. METHODS: Transaction-level purchasing data for food and drink items for at-home (1,221 households) and out-of-home consumption (171 individuals) were available from the GB Kantar Fast Moving Consumer Goods Panel for London and the North of England. The study period included 23rd March to 10th May 2020 ('lockdown'), and the same period in 2019 for comparison. NFE exposures included food outlet density and proximity, and NFE composition within a 1 km network buffer around the home. Associations were estimated for both years separately, adjusted for individual and household characteristics, population density and area deprivation. Interaction terms between region and exposures were explored. RESULTS: There were no consistent patterns of association between NFE exposures and food and drink purchasing in either time period. In 2019, there was some evidence for a 1.4% decrease in energy purchased from ultra-processed foods for each additional 500 m in the distance to the nearest OOH outlet (IR 0.986, 95% CI 0.977 to 0.995, p = 0.020). In 2020, there was some evidence for a 1.8% reduction in total take-home energy for each additional chain supermarket per km2 in the neighbourhood (IR 0.982, 95% CI 0.969, 0.995, p = 0.045). Region-specific effects were observed in 2019 only. DISCUSSION: Findings suggest that the differences in exposure to the NFE may not explain differences in the patterns or healthiness of grocery purchasing. Observed pre-pandemic region-specific effects allude to the importance of geographical context when designing research and policy. Future research may assess associations for those who relied on their NFE during lockdown.

Introduction: although nutritional differences between different types of texture-modified diet (TMD) have been evaluated, the resources and costs associated with their preparation have been less studied. Objective: to describe the nutritional, microbiological properties and costs of: 1) in-home produced pureed food (hTMD); 2) concentrated nutrient-dense commercial food products, hand-blended (cTMD); 3) food prepared using the MixxPro® automatic food mixer (cTMD-Mix). Methods: an observational, prospective study carried out in three geriatric nursing-homes. Patients ≥ 65 years, receiving TMD, with a stable clinical condition, estimated survival/expected internment > 1 month, and sufficient cognitive capacity were included. The following data were recorded: 1) patient socio-demographic and clinical variables; 2) TMD compliance and symptoms related to dysphagia during the meal; 3) patient appetite; and 4) kitchen information and resources used to prepare a TMD. Results: sixty-two residents were included (65.0 % women, 88.3 years (SD: 9.3); 43.5 % malnourished, 79.0 % with good appetite). The proportion of food eaten/median kcal served/portion/mean kcal consumed were: hTMD: 95.5 % (SD: 10.7)/92.4 kcal (IQR: 75.6-128.1)/88.2 kcal (IQR: 72.2-122.3); cTMD: 89.2 % (SD: 15.9)/323.4 kcal (IQR: 284.2-454.1)/288.5 kcal (IQR: 253.5-325.1); and cTMD-Mix: 80.3 % (SD: 21.4)/358.0 kcal (IQR: 344.0-372.1)/287.5 kcal (IQR: 276.5-298.8). No microorganisms were detected. The average time spent in preparing each portion and its costs were: hTMD: 11.2 min (SD: 3.89)/2.33 (SD: 0.63); cTMD: 1.7 min (SD: 0.28)/2.01 (SD: 0.39); and cTMD-Mix: 1.6 min (SD: 0.00)/2.00 (SD: 0.33).

BACKGROUND: to date, gluten-free (GF) diet is the only treatment available for individuals with celiac disease. Both individual and collective food intake assessments are a challenge because a food composition database of GF products (GFPs) is lacking. OBJECTIVES: to describe the process of developing a food composition database of GFPs, and to compare the nutritional profile and price of some GFPs and non-GFPs. METHODS: initially, a total of 216 brands of GFPs marketed in Spain were recorded. Nutritional information was collected from nutritional labels and product fact sheets that had been provided by food companies or collected first-hand by researchers. Then, the nutritional profile and price of the cereal and cereal byproducts foodstuff groups, including 19 types of products, were compared. Statistical analyses were performed using the SPSS statistical program (22.0 edition; SPSS, Chicago, IL, USA). RESULTS: a total of 2,247 GFPs from 126 different foodstuff brands were included in the food composition database of GFPs (CELIAC-BASE). We classified these products into 14 foodstuff groups. The protein content of the GFPs studied was significantly lower, and the price was higher, than that of their non-GFP counterparts. Some, but not all, GFPs had a higher content of fat and sugar, and a lower content of dietary fiber as compared to their non-GFP counterparts. Some GFPs were up to 6 times more expensive than the corresponding non-GFPs. CONCLUSIONS: CELIAC-BASE is a pioneering tool for dietitians. Many GFPs have poor nutritional profiles and should be consumed only occasionally in a balanced GF diet
INTRODUCCIÓN: hasta la fecha, una dieta sin gluten (SG) es el único tratamiento para las personas con enfermedad celíaca. Tanto las evaluaciones de ingesta de alimentos individuales como las colectivas son un desafío debido a la falta de una base de datos de composición de productos SG (PSG). OBJETIVOS: describir el proceso de desarrollo de una base de datos de composición de PSG y comparar el perfil nutricional y el precio de algunos PSG y productos con gluten. MÉTODOS: inicialmente, se registraron un total de 216 marcas de PSG comercializadas en España. La información nutricional se recopiló de las etiquetas nutricionales y hojas informativas de los productos, que habían sido proporcionadas por las compañías de alimentos o recopiladas de primera mano por los investigadores. Luego, se compararon el perfil nutricional y el precio de los grupos de cereales y subproductos alimenticios, incluidos 19 tipos de productos. Los análisis estadísticos se realizaron utilizando el programa estadístico SPSS (edición 22.0; SPSS, Chicago, IL, EUA). RESULTADOS: se incluyeron un total de 2247 PSG de 126 marcas de alimentos diferentes en la base de datos de composición de PSG (CELIAC-BASE). Clasificamos estos productos en 14 grupos de alimentos. El contenido de proteínas de los PSG estudiados fue significativamente menor, y el precio de los mismos fue más alto, que el de sus homólogos con gluten. Algunos PSG, pero no todos, presentaron un mayor contenido de grasa y azúcar, y un menor contenido de fibra dietética, que sus homólogos con gluten. Algunos PSG eran hasta 6 veces más caros que sus homólogos con gluten. CONCLUSIONES: CELIAC-BASE es una herramienta pionera para dietistas-nutricionistas. Muchos PSG tienen perfiles nutricionales no saludables y deben consumirse solo ocasionalmente en una dieta equilibrada libre de gluten

Resumo Um dos maiores problemas atuais da população é a deficiência de nutrientes. Estudos indicam que consumidores consideram o preço dos alimentos mais relevante do que os valores nutricionais. Assim, este trabalho objetivou comparar o custo dos nutrientes de alimentos típicos da dieta brasileira, realizando coletas de preços em mercados virtuais e calculando o custo para se atingir 30% das necessidades diárias de um adulto saudável para oito nutrientes. A carne de frango foi a fonte mais barata de proteína. A fibra de cereal teve o menor custo para fibra e ferro. As fontes mais baratas de cálcio foram o Ovomaltine e os lácteos, e o fígado bovino foi o alimento melhor ranqueado para vitamina A. A vitamina C foi o nutriente mais barato na dieta brasileira, e o suco de acerola a fonte mais barata deste nutriente. Os lácteos ocuparam as seis primeiras posições no "ranking" da vitamina D, e nozes e sementes apresentaram o menor custo para vitamina E. Os resultados mostraram que os consumidores brasileiros podem alcançar a ingestão recomendada de nutrientes considerados críticos a um baixo custo por meio da aquisição dos alimentos melhor ranqueados. No entanto, esse ranqueamento deve ser ponderado em função da qualidade do alimento, conforme preconiza o Novo Guia Alimentar para a População Brasileira.
Abstract Nutrient deficiency is one of the major problems of the human population today. Studies indicate that consumers consider that the price of food is more relevant than its nutritional value. Therefore, this work sought to compare the costs of nutrients provided by typical foods found in the Brazilian diet. Food prices available in virtual markets were collected, and the costs to meet 30% of the daily recommendations for a healthy adult were calculated for eight nutrients. Poultry was found to be the cheapest source of protein. Cereal fiber had the lowest cost for both fiber and iron. The cheapest sources of calcium were Ovaltine and dairy products, whereas cow`s liver was the best ranked food for vitamin A. Vitamin C was found to be the cheapest nutrient in the Brazilian diet, with acerola juice being the cheapest source of this nutrient. Dairy products occupied the first six positions in the ranking of vitamin D, while nuts and seeds were the cheapest sources of vitamin E. The results showed that Brazilian consumers can meet the recommended intake of critical nutrients at a low cost through the purchase of the best ranked foods. However, this ranking should be weighted according to the food quality, as recommended in the New Dietary Guidelines for the Brazilian Population.

Resumo O objetivo foi analisar o investimento financeiro para a aquisição de alimentos destinados à alimentação escolar em um município no Sul do Brasil. As licitações, as chamadas públicas e a prestação de contas do PNAE foram analisadas por meio das variáveis: I) valores de complementação financeira do município; II) percentual de recursos destinado à compra de alimentos da Agricultura Familiar (AF) e aos alimentos Recomendados, Restritos, Proibidos e outros. Comparação de proporções foi o teste utilizado para identificar diferenças entre investimentos. A complementação financeira do município denotou 65% do total. O valor total empregado para a aquisição de alimentos foi: 65,5% Recomendados, 27,9% Restritos, 6,5% Outros e 0% Proibidos. Os gastos com alimentos Recomendados foram maiores (p < 0,001) do que com os demais grupos. A AF forneceu exclusivamente alimentos Recomendados, representando 12,1% do investimento total (municipal e federal) e 29,5% dos recursos federais. A compra direta da AF contribuiu para aquisição de alimentos Recomendados. A complementação financeira do município não foi direcionada à AF, podendo comprometer o potencial do programa de alimentação escolar na promoção de sistemas agroalimentares sustentáveis, saudáveis e locais.
Abstract This study aimed to analyze the financial investment used for the procurement of food for the Brazilian National School Food Program (PNAE) in a city in the South of Brazil. The bidding process, the public calls and accountability reports of the PNAE were analyzed in the following variables: I) municipal financial complementation values; II) percentage of resources used to purchase foods from Family Farmer (FF), and Recommended, Restricted, Prohibited and others foods. The comparison of proportions was employed as a test to identify differences between investments. The municipal financial complementation was 65% of the total. The total amount used to purchase foods was distributed as follows: 65.5% for the Recommended, 27.9% for the Restricted, 6.5% for the Other and 0% for the Prohibited. The expenditure on Recommended foods was higher (p < 0.001) compared to the remaining groups. FF provided only Recommended foods, representing 12.1% of total (municipality and federal) expenditure and 29.5% of total federal funds. The direct purchase from FF contributed to the purchase of recommended foods. The municipal financial complementation was not geared to FA, which can compromise the potential of the school food program to promote healthy and sustainable food systems.
